This is a request for you to implement support for the List- header fields defined in RFC2369. This will make mail list access easier for users. The List- header fields provide you with a standard method by which you can consistently describe electronic mailing list command syntax so that client applications can implement an interface to make list access easier for users. The currently defined fields are List-Subscribe, List-Unsubscribe, List-Help, List-Post, List-Owner and List-Archive. They describe commands for subscribing, unsubscribing, retrieving help information, posting to the list, contacting a human administrator and accessing message archives. Implementation guidelines for list software authors are available at: Extended details on the List header fields are available from: A mailing list for discussion is available at: or Information on the format of mailto URLs: Please let us know if you plan to implement support for the List- header fields, and also if/when you ship an implementation. Thanks!
